The new ISO 19030 hull and propeller performance standard is set to have a huge impact on ship operators’ bottom lines – and the box ship sector is the most suitable for its application
The new ISO 19030 hull and propeller standard has come into force and looks as if it will have a major impact on ship operators’ balance sheets.
The benefits were unveiled at an open forum on the new standard, held in London, UK. The forum was hosted by leading paints and coatings supplier Jotun, class society DNV GL and the Baltic and International Maritime Council (BIMCO) – all driving forces behind the launch of the new ISO 19030.
Stein Kjølberg, Jotun’s global sales director for hull performance solutions, said in an interview: “By applying the standard, ship operators have a tremendous opportunity to have access to more data to analyse performance, both historically and in the future. It enables them to make a decision about the right solution to be applied to a vessel. This does not need to be the most expensive or advanced, but suited to the trade of that vessel. There is a lot of money to be saved by applying this standard.”
He explained how one ship operator saved US$1.8 million in between two drydocking periods after applying the standard – but it could have saved even more if it had applied the standard earlier. “Within the first period there was a significant drop in performance. If it had carried out initiatives and inspections more quickly, it probably could have saved US$1 million – just by doing that,” Mr Kjølberg said.
The standard will bring clarity to the industry, too. “There have been several cases of owners not understanding that the underwater hull is affected if cleaning is delayed, so a lot of fuel is used before they do something about it. By having this standard, a ship operator can analyse and have a better idea of if, and when, it should carry out cleaning and what effect this will have.”
And he singled out the container ship sector as “probably most suitable for the standard. These vessels very much depend on reaching port at a certain time, go at a higher speed, have high fuel consumption, and use more powerful engines, as container ships are being built at a larger scale. So by applying the standard there are significant savings for container vessels.” He said that almost half of all ships for which Jotun has signed contracts are container vessels.
The standard is just the beginning. “It is a good start. Ideally you should have a set up that can measure every step of the way – not just hull and propeller monitoring, but also engine management, crew management … There should be a chain of different initiatives that identify ship efficiency,” Mr Kjølberg said.
Tobias Gröger, DNV GL senior consultant for maritime performance solutions, Western Europe, added: “It is one tiny element of big data.” He said that sensor data could also be connected to other data, including weather and fuel analytics information. “This big data will, in the long run, put shipping companies in a position where they can look at what they can do to increase vessel efficiency.”
The standard will be revised and – based on what has been learned – updated every three years. Mr Kjølberg said: “We expect the standard to be refined and revised and made simpler to use and more accurate. More default methods will be put in so there is more variety. But there will be the same KPIs, so it will be open, transparent and equal.”
AkzoNobel was also involved in developing the standard. Michael Hindmarsh, business development manager at AkzoNobel’s marine coatings business, hailed the ISO 19030 standard as an “important milestone in the shipping industry’s continued journey towards enhanced monitoring of hull and propeller performance.”
He said that as ISO 19030 is still relatively new, AkzoNobel is working with the industry to assess its appetite for the standard. “We believe ISO 19030 represents a solid, initial ‘line in the sand’ in relation to monitoring hull and propeller performance, but there is still further progress that needs to be made,” he said.
“That is why participants involved in developing the standard are advocating that the industry – including ship performance monitoring specialists such as BMT Smart, Wärtsilä-owned Eniram, Marorka and NAPA – embrace ISO 19030 as a minimum requirement and adapt their performance monitoring systems accordingly. In addition, to ensure the continued relevance of the standard, it is essential that ISO 19030 keeps pace with the ongoing development of technology and analysis capabilities that ship performance monitoring specialists are currently developing.”
Hull coating predictions from Intertrac Vision – AkzoNobel’s big data consultancy tool for ship operators that provides predictions about the fuel and CO2 savings potential of fouling control – can be verified and validated against actual performance using monitoring processes that are compliant with ISO 19030. Since the launch of Intertrac Vision in October 2015, its consultants have visited 26 container ship owners and operators.Mr Hindmarsh said that the predictions provided by the technology have so far received positive feedback.
He summed up by saying that new big data technologies such as Intertrac Vision have a role to play in supporting container ship owners and operators “in making the right hull coating selection that will have maximum impact on fuel and emissions savings targets.”
He highlighted: “When combined with industry wide initiatives such as ISO 19030, it is possible for the industry to make considerable progress in terms of selecting and measuring the impact of hull coatings on wider sustainability aspirations.”
The main challenge of applying the standard is the handling of the sensors to collect the data needed. Mr Gröger added: “The challenge is to ensure that they are well calibrated and well maintained and that people know how to read data.”
But an important benefit is the way in which data is exchanged (slow frequency data). “Ninety per cent of all companies have traditional manual ship-shore data in place. This means that in terms of data collection, nothing changes for shipping companies. They do not have to adjust or make changes in their reporting lines,” Mr Gröger explained.
